SMA Connector Plug 50 Ohm Solder (Amphenol RF 132124)

Part Overview

The Amphenol RF 132124 is an SMA connector plug with male pin configuration, designed for 50 ohm coaxial cable termination using solder contact attachment. This free-hanging (in-line) connector operates across a frequency range up to 12.4 GHz and is suitable for RF/microwave applications requiring reliable signal transmission. The part is currently active in production with 1159 units in stock. Equivalent substitute parts may be required due to supply chain considerations, design standardization across manufacturing partners, or specific cable compatibility requirements within system integration workflows.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol RF 132124 with the Cinch Connectivity Solutions 142-0203-011 is based on strict electrical and mechanical parameter alignment. Both connectors share identical core specifications: SMA connector style, male pin plug configuration, 50 ohm impedance, solder contact termination, clamp shield termination, free-hanging in-line mounting, threaded fastening, 12.4 GHz maximum frequency, 500 mating cycles, and identical operating temperature range (-65°C to 165°C). Both parts maintain ROHS3 compliance and MSL 1 rating. The substitute part accommodates a broader cable group compatibility (RG-161, 174, 179, 187, 188, 316 versus RG-174, 188A, 316 for the main part), supporting expanded application flexibility. The primary distinction is the voltage rating differential (250 V for substitute versus 500 V for main part) and dielectric material composition (ETFE/PTFE for substitute versus PTFE for main part). Both parts are active production items with established supply availability.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 132124 and Cinch Connectivity Solutions 142-0203-011 are active production components with full ROHS3 compliance and REACH affected status. Selection between these parts should be based on application voltage requirements. The Amphenol RF 132124 is specified for 500 V operation, while the Cinch substitute is rated for 250 V. Applications requiring the full 500 V rating must use the Amphenol part. For applications operating at or below 250 V, either part is electrically suitable. The Cinch part supports a broader cable group range (RG-161, 174, 179, 187, 188, 316), providing greater flexibility in cable selection. Both parts maintain identical frequency performance (12.4 GHz maximum), temperature range (-65°C to 165°C), and mechanical durability (500 mating cycles). Dielectric material composition differs (PTFE for Amphenol versus ETFE/PTFE for Cinch), which may influence performance in specific environmental or frequency-dependent applications. Packaging format differs (Bag for Amphenol versus Bulk for Cinch), affecting procurement and inventory management considerations.

Frequently Asked Questions (FAQ)

Q: Can the Cinch Connectivity Solutions 142-0203-011 directly replace the Amphenol RF 132124 in all applications?

A: Direct replacement is possible for applications operating at or below 250 V. The Amphenol part is rated for 500 V operation, while the Cinch substitute is rated for 250 V. Applications requiring 500 V operation must use the Amphenol part. All other electrical and mechanical parameters are equivalent.

Q: What is the significance of the cable group differences between these two parts?

A: The Amphenol RF 132124 is specified for RG-174, 188A, and 316 cable groups. The Cinch 142-0203-011 supports RG-161, 174, 179, 187, 188, and 316 cable groups. The Cinch part accommodates a broader range of coaxial cable types, providing greater design flexibility. Both parts are compatible with RG-174 and RG-316 cables.

Q: Are there differences in dielectric material between these connectors?

A: Yes. The Amphenol RF 132124 uses polytetrafluoroethylene (PTFE) dielectric material. The Cinch 142-0203-011 uses both ethylenterafluorineethylene (ETFE) and polytetrafluoroethylene (PTFE). PTFE offers superior high-frequency performance and lower dielectric loss, while ETFE provides enhanced mechanical flexibility. Material selection should align with specific application requirements.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the Amphenol RF 132124 and Cinch 142-0203-011 are ROHS3 compliant, REACH affected, and classified under ECCN EAR99 with identical HTSUS code 8536.69.4010. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What are the packaging differences, and how do they affect procurement?

A: The Amphenol RF 132124 is supplied in Bag packaging, while the Cinch 142-0203-011 is supplied in Bulk packaging. Packaging format affects inventory management, handling procedures, and minimum order quantities. Verify packaging requirements with your procurement specifications before ordering.

Q: Are the included components identical between these two connectors?

A: No. The Amphenol part includes 8 pieces (1 Connector, 1 Clamp, 1 Contact, 1 Gasket, 1 Insulator, 1 Top Hat, 2 Washers). The Cinch part includes 6 pieces (1 Connector, 1 Clamp Cone, 1 Clamp Nut, 1 Clamp Stem, 1 Contact, 1 Insulator). Component kit differences may affect assembly procedures and spare part requirements.

Q: What is the maximum operating frequency for both connectors?

A: Both the Amphenol RF 132124 and Cinch 142-0203-011 are specified for 12.4 GHz maximum frequency operation. Frequency performance is identical between the two parts.

Q: Can these connectors be used in high-temperature applications?

A: Yes. Both connectors are rated for operating temperatures from -65°C to 165°C, supporting extended temperature range applications. This specification is identical for both parts.
